Question 297

You had setup the VPN Community 'VPN-Stores' with 3 gateways. There are some issues with one remote gateway(1.1.1.1) and an your local gateway. What will be the best log filter to see only the IKE Phase 2 agreed networks for both gateways.

    Correct Answer: B

    The correct log filter to see the IKE Phase 2 agreed networks is 'action:"Key Install" AND 1.1.1.1 AND Quick Mode'. IKE Phase 2 is also known as Quick Mode, so the filter must include Quick Mode to capture the relevant logs. Including 'Key Install' focuses on the establishment of the SA (Security Association) which occurs during Phase 2, and '1.1.1.1' ensures that the logs displayed are specific to the remote gateway with issues.

Discussion
McBeanoOption: B

"IKE Phase 2 occurs after phase 1 and is also known as quick mode and this process is only 3 packets." https://ccie-or-null.net/2012/03/26/ike-main-mode-aggressive-mode-phase-2/ So it must be B or D. I'd be leaning towards B, with the question specifying that only 1.1.1.1 has issues. D would presumably show logs for all 3 gateways in the VPN-Stores community.

AraminskiOption: B

IKE Phase1; two options: Main Mode or Aggressive Mode IKE Phase2 = Quick Mode (similar to Aggresive Mode on P1, 3 packets negotiation) So, "A" and "C" are out because are related with Phase 1, about "D" it's not the best filter to see the issue about the remote gateway with IP address 1.1.1.1 (remeber there are 3 gateways….) Correct answer i think its "B"

cha_dadi_examsOption: C

The correct answer is C . Key install is phase 1 and the question is about phase 2 . So A and B are out . So is it C or D . I will choose C cause main mode is the default .
